The study was carried out to determine the relative efficacies of polyphenolic flavonoids, quercetin, catechin and epicatechin against tert-BOOH induced oxidative stress in human macrophage, U-937 cell line. Exposure of the cells to tert-BOOH oxidative stress resulted in a significant increase in cytotoxicity and reactive oxygen species (ROS) generation.(More)
The present study reports cytoprotective and antioxidant activity of aqueous and alcoholic extracts of Rhodiola imbricata rhizome on tert-butyl hydroperoxide (tert-BHP) induced cytotoxicity in U-937 human macrophages. There was an increase in cytotoxicity and apoptosis significantly in the presence of tert-BHP over control cells. The tert-BHP induced(More)
tert-Butylhydroperoxide has been reported to inhibit growth and induce apoptosis in number of cell types, but little is known about the molecular mechanism mediating these effects. In the present study, we determined the molecular pathways that lead to apoptosis after treatment of cells with t-BOOH. The cells were exposed to different concentrations of(More)
